Same 155cc engine, but the performance completely changes depending on your right wrist. 🥵

That's the magic of Yamaha's VVA system. It’s entirely mechanical —under 7,400rpm, the bike stays smooth and easy to ride in traffic. But once you push past that mark, it switches to a wilder cam profile and turns into a high-revving highway beast.Best of both worlds, honestly.🎀💬R15, MT-15, or Aerox 155 - which one handles that VVA kick best?
